8-CHANNEL SOURCE DRIVER
This versatile integrated circuit will work with many combinations logic- load-voltage levels, meeting interface requirements beyond capabilities standard logic buffers. UDN2585A A2585SLW source drivers drive incandescent, LED, vacuum fluorescent displays. Internal transient-suppression diodes permit drivers used with inductive loads such relays, solenoids, stepping motors, magnetic print hammers. UDN2585A A2585SLW drivers designed applications requiring output saturation voltages. Typical loads low-voltage LEDs incandescent displays. eight non-Darlington, outputs will simultaneously sustain continuous load currents -120 ambient temperatures +70°C. These drivers packaged plastic DlPs (suffix surface-mountable wide-body SOlCs (suffix LW), rated operation over temperature range -20°C +85°C.
